CHART-PUZZLE.

Specification of Letters Patent.

` Patented Aug. 3, 1915.

Application filed January 15, 1913, Serial No. 742,123. Renewed April 6,1915. Serial No. 19,557.

To all whom 'it may concern:

Be it known that I, EDWARD J. BARRETT, a citizen of the United States,and resident of Sheboygan, in the county of Sheboygan and State ofWisconsin, have invented certain new and useful Improvements inChart-Puzzles; and I do hereby declare that the following is a full,clear, and exact descri tion thereof.

y invention has for its object to provide a simple, economical anduseful educational chart puzzle, the same consisting of what is hereindescribed with reference to the accompanying drawings and subsequentlyclaimed.

In carrying out my invention I propose to utilize a chart ofchronologically tabulated historical or biblical events, or charts ofvalues, areas or the like.

In the drawings Figure l represents a chart puzzle showing thePresidents of the United States in their chronological order, togetherwith the terms of office of each President, the said chart beingprovided with removable blocks having the names of the variousPresidents thereon, the blocks being of various proportions relative tothe terms of such Presidents, and Fig. 2, a face view of a miscellaneousgroup of the blocks, the same being arranged to fit within the chartbody in their order.

Referring by characters to the drawings,

1 represents a chart body having a headline of periods indicated bydates from 1787 to 1905 inclusive. These headline dates are arbitrarilyspaced apart to represent a series of historical units, the samecomprlsmg one term of oliice of four years. Directly below the headlinedates the body of the calendar is cut away into blocks 2 having1rregular edges that are adapted to fit corresponding upper and lowerirregular cut edges of the body of said chart and also having side edgesadapted to articulate with each other when said blocks are seated in ltheir proper relative positions. Each of the blocks has printed thereonthe name of a President and for example, the rst block of the series hasprinted ,thereon the name of the firstAPresident, George Washington, thesecond John Adams, and so on up to a block having the name ofvPres1dentRooseveltvthereon, which block is adapted to lit under the date 1905,the last named block being shown as one of the group 1n Fig. 2.

All of these blocks are proportioned so as to approximately correspondin relative areas to the length of time served'by the name of thePresident thereon, and, for example, the last block tted in the chart,marked Abraham Lincoln, is cut into L shape indicating that his term ofoce was interrupted during a second period and the remainder of saidsecond'period is formed into a separate block with the name of thePresident Andrew Johnson who filled out the unexpired term, these twomen having together completed two terms. The single term of ZacharyTaylor having been interrupted, was, as shown by the chart, filled outby Millard Fillmore, attention being called to the fact that thesebroken terms are shown by sectional cubes or blocks, in relativeproportions to the time served.`

In solving the puzzle, it is apparent'that when the blocks are stackedin a detached group the scholar being required to replace the same intheir order with reference to the date line of the chart body, can, withalimited knowledge, in a general way, determine the positions of thevarious blocks by read-l ing the headline dates, it being apparent bygiving the matter some thought, that the block having the name thereonof James Madison would not fit under any of the dates high up in thechart and with this clue the said block can readily be fitted under therightperiod and so on throughthe entire chart body aperture, each blockis fitted to its period. Thus in an assembling of this character, thechild is called upon to use some judgment andk general knowledge, whileafter so applied it is apparent that the physical arrangement of theblocks will have a tendency to impress upon the student firmly thehistorical events so charted in their chronological order.

The chart illustrated simply shows one example of carrying out myvinvention, it being understood that the same principles can be appliedto biblical puzzle charts, periods of finance, compilation of values oranalogous data for educational purposes to thus impress the subject andthe arrangement more firmly upon the mind.

I claim:

1. A puzzle chart comprising a body provided with arbitrarily arrangedindices and having blocks irregularly cut from the chart body under theindices, the proportionate area of each block approximating the value ofthe index under which it is adapted to fit, the blocks being providedWith symbolic markings associated with the indices.

2. A puzzle chart comprising a body provided with chronologicallyarranged dates blocks being provided with suitable markings associatedWith said dates.l

In testimony that I claim the foregoing I have hereunto set my hand, atPort Washington, in the county of Ozaukee andState of Wisconsin, in thepresence of two Wit nesses.
